Kimmons entered the UFC in 2008 with a stellar 21-3 record. However, he’s since rotated between wins and losses with victories over Rob Yundt, Joe Vedepo and Steven Steinbess, and defeats came to Dan Miller, Jorge Rivera and Kyle Noke. The Missouri-based fighter’s most recent win, which came over Steinbess, was his first victory via decision in 10 fights and four years. Nineteen of his 23 career wins have come via stoppage, 14 via submission.

Yang, a former DEEP and Sengoku fighter, signed with the UFC in 2010 after posting a 9-0 mark, which included eight consecutive TKO victories. However, in his octagon debut, the Korean fighter suffered a split-decision defeat to Chris Camozzi at UFC 121.
